LPC2xxx internal flash driver

Hi Sergei

I note that Hans Rosenfeld's LPC2xxx flash driver package
(CYGPKG_DEVS_FLASH_ARM_LPC2XXX) is not referenced by any target at
present. There are 7 LPC2xxx targets which could potentially make use of
this hardware package. Can you see any reason why we should not add the
package to the various LPC2xxx target definitions in ecos.db (including
your own contributed ports)?

FYI, the driver uses a buffer ending at 0x40004000 in internal SRAM.
